Textual Form

Container element for use only inside <alternatives> that will hold text and mixed content as an alternative to, for example, a graphic.


The typical case is inside a display equation (<disp-formula>), when the formula is present in several forms, for example as a MathML encoded equation, a plain text alternative which uses ASCII characters and superscripts, and a <graphic>. The text alternative is coded as a <textual-form> element.
